Abstract :

The structure and properties of niobapyrimidinium complex were examined by density functionaltheory method (mpw1pw91). The effect of solvent on the structural parameters, frontier orbitalenergies and hyperpolarizability (tot) of this molecule has been explored. The thermodynamicproperties of the title compound at different temperatures have been calculated. Also, the parasubstitutionseffect on the structure, frontier orbital energies, aromaticity and hyperpolarizability (tot)has been studied. Nucleus independent chemical shift (NICS) values show that these species arearomatic.
